Patent DE-2545447-A1 (DE)
Title: Resistor trimming using voltage higher than operating one - cools resistor down to ambient temp. in repeated steps
Inventor: DIESING WOLF
IPC: H01L21/326
Filed: 1975-10-10
Abstract: The trimming is carried out to a preset resistance value. After manufacturing of the resistor a voltage is applied, which is higher than the operating voltage, but lower than the resistor destructive voltage. The voltage application for a certain time heats up the resistor. The latter is then cooled down to ambient temperature by the voltage switching off. These two steps are successively repeated until the desired precision of the resistor has been attained. Preferably the resistor is produced by thick film technique by deposition of respective layers on an insulating substrate, the layers being either conductive or semiconductive. Alternately it can be produced by thin-film technique or as a monolithic module.

Title: Tape recorder single motor positive drive - has frictional couplings replaced by gear wheels for constancy of speed and torque
Inventor: STRAUSAK BENEDIKT
IPC: G11B15/44
Filed: 1976-01-02
Abstract: Drive system for a tape recorder uses a single motor driving the tape spool through a coupling with normal and fast drive settings and through belts and flywheels. The coupling takes the form of a toothed wheel which engages with a drive wheel of the spool in the 'normal' setting and which is integral with intermediate gears which engage with gears of the spool in the fast drive position. The arrangement gives constancy of speed and torque comparable with that of a more expensive multi-motor drive but is applicable to small cassette recorders and dictating machines. This results from the elimination of the normal frictional drive.

Title: Sprayed absorber cell type air humidifier - has parallel absorber plates curved in direction of air flow (CS 31.5.77)
Inventor: NOVAK STANISLAV
IPC: B01D47/06
Filed: 1976-07-17
Abstract: The humidifier has rectangular cells (1) with open front and back through which the air flows. Water is sprayed onto the cells from jets (2) in the direction of air flow and the cells contain a large number of parallel plates (9) on the surface of which the water evaporates into the air stream. The plates are curved in the direction of the air flow to an extent such that the difference in height between the end and centre of each plate is greater than the vertical spacing between the plates. This prevents unevaporated drops of water being carried through the cell and thus improves the efficiency of humidification and reduces the quantity of water which has to be sprayed in.
